NEW ORLEANS â?? Two players received personal foul penalties after a post-interception scrum, but Baltimore cornerback Cary Williams was not flagged after he shoved a referee with two hands.

Replays clearly show Williams shoving an official who was trying to break up a shoving match among players from both teams following Ed Reed's second-quarter interception. Referees threw multiple flags, but only San Francisco offensive tackle Joe Staley and Baltimore cornerback Corey Graham received the offsetting unnecessary roughness penalties.

Touching a referee can result in ejection, though that decision is a judgment call handled on the field by the officiating crew.

On Baltimore's next defensive series, Williams nearly intercepted Kaepernick when he deflected a pass deep in San Francisco territory.
